Field of the InventionThis invention relates generally to structures for enclosing books formovementthrough the mails, the structure being characterized by cells ateach end thereof protecting the ends of the book therein.

2. The Prior Art Structures of this general kind are illustrated inSkaggs U.S. Pat.No. 3,l16,005 (Class 229/40).

SUMMARY OF THE INVENTION According to the present invention goodprotection is provided for a book during shipment by the provision of acell disposed at each end of the shipping folder, the cell beingcharacterized by an element extending in contact with one end of a book,a second element extending substantially in planar relationship with awall of the folder, and an oblique member defining with the otherelements a protective deformation resistant cell of generally triangularcross section.

THE DRAWING FIG. 1 is an isometric view of a closed shipping folderaccording to the present invention;

FIG. 2 is a plan view of a cut and scored blank for forming the shippingfolder of FIG. 1;

FIG. 3 is a perspective view showing steps in forming the folder of FIG.1;

FIG. 4 is a view looking in the direction of the arrows 4-4 of FIG. 3;

FIG. 5 is a sectional view taken along the line 5-5 looking in thedirection of the arrows.

The cushioned shipping folder according to the present invention isreferred to generally by the reference numeral and is formed from a cutand scored blank 10A consisting of a pair of major parallel walls 11 andminor parallel walls 12 foldably interconnected along fold lines 13. Anouter closure flap 14 is connected to one of the minor parallel walls 12along a fold line 16, and a flap 14 is connected to the remote majorwall 1 1 to form a tubular structure.

The folder according to the present invention is adapted to enclose abook B resting upon one of the major parallel walls 11 seen in FIG. 3,and closure structure is provided for each end of the folder l0, andcomprises a first inner flap l9 and a second inner flap l7 foldablyconnected to each other along a fold line 18. First inner flap 19 isconnected to a major parallel wall 11 by means of spaced score lines 21and 22, there being a score panel 23 therebetween. An interrupted cutline 24 flanks the two score panels 23.

As seen in FIG. 3, the inner flap 19 is folded to a position in facingrelationship to the major parallel wall 11, and the second inner flap 17is folded perpendicular to the first inner flap l9 and the majorparallel wall 11 to lie against a book B seen in FIGS. 4 and 5.

a fold line 27.

With the book B in position between the second inner flaps 17, the othermajor panel 11 is brought over the book B. First outer flap 26 is foldedto the position seen in FIGS. 3 and 4, and the second outer flap 28 isfoldably connected as seen in the said figures and secured to the outerside of the first major wall 11, thereby creating an essentiallytriangular shaped cell protecting opposite ends of the book B. I

After the formation of the end cells seen more clearly with respect toFIGS. 4 and 5, the outer closure flap 14 is brought around and securedto the outside of panel 11. The ends of the closure flap 14 are miteredat 31 and contiguous ends of the second outer flaps are mitered as at32, so that the flaps 14 and 28 may fit against each other.

Minor parallel wall 12 is likewise mitered at the ends 33 to fit snuglyagainst the first outer flap 26 when the same is brought to the obliqueposition seen in FIGS. 4 and 5. v

I claim:

1. A cushioned shipping folder formed from a unitary blank of foldablepaperboard or the like, comprising:

a. opposed pairs of major and minor parallel walls foldablyinterconnected to form a tubular structure;

b. an outer closure flap foldably connected to one of said parallelwalls and secured to an adjacent parallel wall of said tubularstructure;

c. a closure structure for each end of said tubular structure, saidstructure comprising:

i. a pair of first andsecond inner flaps foldably connected to eachother with one of said flaps being foldably connected adjacent to oneend of said major parallel wallsz- A. said first inner flap being foldedto a position in facing relationship to said one major parallel wall;

8. said second inner flap being folded perpen- I dicularly with respectto said first inner flap and said one major parallel wall;

ii. a pair of first and second outer flaps foldably connected to eachother with one of said outer flaps being foldably connected to one endof the other of said major parallel walls:

A. said first outer flap being folded to an oblique position in contactwith edges of said inner flaps;

B. said second outer flap being folded along and secured to the first ofsaid major parallel walls;
